"It's a mixture of all manner of business conditions, so yes there's currency (pressure) but at the same time we have to understand what the demand is. We have to make a return. We monitor (pricing) on all vehicles on a monthly basis. Demand and supply are always factors in pricing, that's the nature of pricing."

Mr Whickman added: "At the end of the day, when you reflect on 4000 orders, that's a pretty big order bank."

The Mustang is half the price it used to be in Australia in the early 2000s -- when a handful of cars were converted from left-hand-drive to right-hand-drive locally -- but local buyers still pay up to $20,000 more per vehicle than they do in the US, even once equipment changes have been taken into account.

"I think it represents pretty good value," said Mr Whickman. "It's still got to get here, it's got to go through a few hoops, it's got to get fumigated, it's got to through the Panama Canal, it's still got to get on a ship."

Mr Whickman said the fall of the Aussie dollar versus the US currency "is a bit of a challenge and the same we have to recoup costs".
